RAIL-ANCHOR AND MANUFACTURE THEREOF.

Specification of Letters Patent.

Patented June 17, 1919.

Application filed April 8, 1919. Serial No. 288,645.

To all whom it may concern:

Be it known that I, EMIL O. BANNER, a citizen of the United States, residing in the borough of Westmont, in the county of Cambria and State of Pennsylvania, (whose post-office address is Johnstown, Pennsylvania,) have invented certain new and useful Improvements in Rail-Anchors and Manufacture Thereof; and I do hereby dc clare the following to be a, clear and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in the form and construction-and manufacture of rail anchors of the kind which are adapted to be clamrkd upon a spring pressure of the rail anchor itself, causing certain parts of said anchor to be elastically bent to produce 'a powerful of said anchor thereon, I

My rail anchor is formed of a her of steel, preferably of hard or spring steel the ends of which are bent over toward each other forming clamping-j aws ate portion of which is bent toward the space between said'jaws, the whole being constructed in such a way that when the anchor is inserted below the rail and itslonger end-placed over one side of the rail flange this allows the shorter end to clear the ed'geof theoppositerail flange, whereupon the other end of the anchor having the shorter bent end portion is moved upwardly so that the lower surface of the shorter bent end contacts with the upper surface of said rail flange adjacent thereto and the anchor is driven thereon with considerable force. thereby clampingit finally in positiom In order to insure that the elasoicrlamping action will besuilicientsmyrail anchor is formed in such a way that the distance between the inner surfaces *of the bent over ends of the rail anchor and the upwardly projecting intermediate portion of the same is less than the corresponding dimensions of the rail flanges, thereby causing the rail anchor to be distorted or elastically sprung in such a way that it exerts a powerful resilient spring pressure on the rail flanges, thereby holding the rail anchor very firmly thereon. As, however, the bent portions of said rail anchor are subjected to severe bending stresses 1, therefore, in order to econorail flange by the to'augrelitcr or less ('legi'ee elamplng action on the rail flange to preventth'e displacement andthe intermedimize material and to make a much more efficient anchor which is both stiller and stronger at less weight and expense, make the rail anchor deeper at those portions which are subjected to the greatest concentrations of cross-bending stresses. In order to accomplish this practically I take a bar of steel which may be approximately square, rectangular or of other suitable section, and in the rolling mill 1 form protuberuntws at predetermined locations thereon which protuberances may be of the same width as 'o'r somewhat narrower than the bar, thus ca-usin a deepening of the same at'int'ervels pre erably, though not necessarily in one direction. I locate these deeper portions at'such intervals along the length of'the bar that when the bar is cut into lengths for for-min into rail anchors,the deeper fortions wili come at the end curves and at be intermediate bent portion in such a way as to strengthen and stifl'en "those parts which are subjected to the greatest cross bending stresses, due to the elastic distortion in spring clamping the anchor upon therfil l flan es.

j Having thus given a general description of my --invention, I will now, in order to makethe matter "more clear, refer to'the annexed sheet of drawings, which forms art of this specification and in which like (5 a1 asters denote like parts Figure 1 is a side elevation of a portion of railway track with my improved rail anchors attached to the rails illustrating the application of my invention. Fi 2 is a vertical transverse sectional elevation taken on the/line II-II of Fig. 1. Fig. 3 is a top plan view from which my rail anchors are made. Fig. 4 is a transverse section of the bar taken on the line 1VIV of Fig. 3. 5 is a transverse section of the bar taken on the'line V-sv of Fig. 3. Fig. 6 is a cross section of a bar through the protuberance which is of substantially the same width as the bar.

Referring now to the numbers of referonce on the drawings :-1 indicates the rail in general, 2 are the rail base flanges, 3 are the railway ties against which the anchors abut to prevent creeping of the rails and 4 are the spikes which partially secure the rail on the ties. 5 represents generally the bar from which my rail anchors are made, this being illustrated as of substantially of a rolled or forged bar or it may be rectangular, round, or" any other suitable section as'will be readily understood.

lengths from which to form rail anchors, the bar is provided with-integral protuberances 9 and 10 which may lac-formed in the rolling mill, or by forging, hammering or otherwise, these protuberances causing the bar to be deeper where they occur and if they are formed from'the metal of the bar the body of which is of finished slze, they are preferably thinner than the bar tself, but I can, if desired, makethem as thick or almost as thick as the body of the, finished bar, by using ,a larger section of bar from which to form thesmaller sections, as illustrated .in Fig. 6, with protpberances.

My rail anchor is placed in position by inserting it under the rail and slipping the longer end 8 over the rail flange toward the rail web, whereupon the shorter end 7 can be swung upwardly so as to clear the edge of the opposite flange, after which the shorter end 7 is driven forcibly upwardly on the opposite rail flange and springs or elastically bends the anchor by reason of the contact of the intermediate portion 12 9,1 the ,deeper intermediate,- (preferably,

e rail flanges with the lower portion of therail base, this springing being facilitated by the angle or slope of the upper surface of the flange, thus s I causing a Wedging action as the shorter end At intervals prior to cutting the bars in is driven on the flange. Although I have described and illustrated my invention in considerable detail, I do not wish to ibe limited to the exact and specific details thereof as shown and described, but may use such modifications in, substitutions for, or equivalents thereof 'as are embraced within thenscopeofmy invention, or as pointed outtin the; claims.
